l l 1 claim.

This invention relates to improvements in coin handling mechanisms, and has as one of its important objects the provision of an improved slide structure for use with coin slides of the reciproeating slide type.`

Another object is the provision in a coin chute having a frame, of a reciprocable slide 0f channel-shaped cross section and greatly increased rigidity.

Another object is the provision of a coin chute including a frame providing a guide sleeve, and a coin slide of channel-shaped cross section slidably mounted in the sleeve, the latter having groove formations along its longitudinal marginal portions in which the opposite side wall portions of the slide channeling are slidably tted, whereby a smoother action and greatly strength of the slide is obtained.

Yet another object is the provision of a coin sleeve is provided with grooves formed to receive a channel slide to increase the resistance of the of the annexed drawing in which like reference characters represent similar parts throughout and in which:

Fig. 1 is a top plan view of the improved coin handling device;

Fig. 2 is a vertical side cross section through the chute along lines 2-2 of Fig. 1;

Fig. 3 is a fragmentary bottom plan view of the device of Fig. 2 as seen along lines 3`3 therev Fig. 4 is a front vertical section through the slide andsleeve along lines 4 4 of Fig. l; while Fig. 5 is a rear end elevation of the slide and sleeve structure as seen in the directionof lines 5--5 of Fig. 2.

The invention relates to a class of coin chute such as shown in Fig. 1-` and which includes a frame or support having a transverse mounting plate I0 adapted for mounting on the wall of a cabinet or the like, and a guideor sleeve formation extending in opposite directionson veither side of the transverse mounting plate so as to provide a front sleeve section I I and a rear sleeve section I2, the front sleeve sectionv normally proincreased y chute of the type described in which the slide jecting outwardly of the cabinet, that is to say, beingexposed and accessibleto the operator of the vending, amusement, or other coin-controlled device with which the chute is usedfwhile the inner sleeve sectionlZ projects interiorly'of the. cabinet or housing and is inaccessible to any but the proprietor. 'l

In the embodiment shown for purposes vof illustration herein, the mounting frame is preferably made in two complementary upper and lower half sections I3 and I4, secured together by means of screws I5 or the like (Figs. 2,3 and 4) and cast or otherwise formed to provide a hollow sleeve portion in which is slidably mounted a coin slide I6.

The slide I6 is of channel-shaped cross section and may be made from a stamping of relatively heavy gauged metalA with anend portion turned upto provide a handle H and opposite longitudinal edge portions upset to provide edgewise f tongues or flanges I8 constituting the upset sidewalls of the channel, in a manner of speaking.

In the bottom section I4 of the frame casting (Fig. 4) there are provided a number of longitudinally extensive grooves I9 inl which various depending formations 20 (Fig/1) ride when the slide is reciprocated, these latter formations functioning as part of the coin handling mechanism.

Along the longitudinal margins of the sleeve or bore in which the slide reciprocates, there are grooves or tracks ZI (Figs. 4 and 5) into which. the tongues or flanges I8 of the slide t closely. The tongues or anges I8 preferably Iextend throughout the length of the slide and provide for smooth operation of the same during its re-l ciprocating motion.

It may be observed that the afore-mentioned channel-shaped cross section of the slide, as viewed in Fig. 4 for example, and particularlythe upset side portions or tongues vI8 thereof, provide for greatly increased structural'strength which makes the slide more highly resistant to deforming stresses which would warp or` bend the or-y dinary slide in a lateral sense.

It frequently occurs that fraudulent attempts to manipulate the slide by. applying unusual bending and deforming forces thereto result-in bending the slide out of shape o-r breaking it off altogether, so that for a given material and die' mensional specification, the length of the slide must be kept within certain limits to reduce this.

, danger to a minimum. 'I'his practice, therefore, restricts the length of the "slide vand as a consequence the length of the strokev which a particular construction of slide may have, and

of appreciable dimensional extent, make it eX-,

tremely dicult to introduce shim Wires and similar defrauding instrumentalities along the longitudinal edges of the slide for projection back into the detent and coin selecting mechanism, there being less lateral play with this type of slide than in the case of the ordinary flat slide as a consequence of the reduced clearances between the longitudinal edge portions of the slide and the sleeve.

As seen in Fig. 4, it will appear that the longitudinally parallel grooves 2| are formed in one of the complementary sleeve members I4, while the other sleeve member is recessed as at I 3a to receive the slide and secure the same in position, and, in addition, block entrance of defrauding feelers and the like.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

In a coin slide of the class described, a coin slide structure and mounting means therefor comprising a pair of complementary sleeveforming members of elongated form, one of which has a pair of longitudinally extending grooves adjacent its opposite long edges, and the other of which is recessed to provide in assembled relation with the first-mentioned member a mounting sleeve for a coin slide member, means for securing said complementary members in assembled relation, and a coin slide of elongated form having opposite longitudinal edges turned up so that the slide is substantially channelshaped in cross section; said slide being tted into said sleeve with each of said up-turned edges fitting closely into one of said grooves in the first-mentioned sleeve-forming member and the side of said slide opposite said edges fitting closely into said recessed part of the other sleeve-forming member, whereby said slide is supported for smooth sliding movement and is rigidied against lateral stresses.
